This problem has been solved! see the answersuppose we examine the distribution of scores on the last exam separately for freshman and sophomores. both distributions are approximately normally distributed and have the same mean, but the distribution of exam scores had a smaller standard deviation among sophomores than freshman. a z-score is calculated for mary’s exam score relative to both distributions (freshman and sophomores). given that mary’s score is well above the mean, which of the following would be true about these two z-scores? a. the z-score based on the distribution for the freshman students would be higher. b. the z-score based on the distribution for the sophomore students would be higher. c. the two z-scores would be the same. d. there is not enough information to determine

1. an economy consists of three workers: larry, moe, and curly. each works 10 hours a day and can produce two services: mowing lawns and washing cars. in an hour, larry can either mow one lawn or wash one car; moe can either mow one lawn or wash two cars; and curly can either mow two lawns or wash one car. a. calculate how much of each service is produced under the following circumstances: a. all three spend all their time mowing lawns. b. all three spend all their time washing cars. c. all three spend half their time on each activity d. larry spends half of his time on each activity, while moe only washes cars and curly only mows lawns b. using your answers to part a, draw a production possibilities frontier and label points a, b, c, and d on your graph. explain why the production possibilities frontier has the shape it does. c. are any of the allocations calculated in part a inefficient? explain.
